According to recent studies, it is estimated that around 35 billion Earth-like planets exist in our galaxy. While this is still a rough estimate, it is likely that there are a significant number of planets that could potentially support life or already harbor living organisms. Option A is incorrect as there is evidence to suggest that Earth-like planets are much more common than previously thought. Option B is also incorrect, as a few million Earth-like planets would be a small fraction of the total number of stars in the galaxy. Option D is incorrect as it is unlikely that every single star in the galaxy has an Earth-like planet orbiting it, given the diversity of planetary systems that have been discovered so far.
